Yan Xu updated MESOS-3424:
--------------------------
Description:
So far AppC store is read only and depends on out of band mechanisms to get the
images. We need to design a way to support fetching in a native way.
As commented on MESOS-2824:
It's unacceptable to have either have:
* the slave to be blocked for extended period of time (minutes) which delays
the communication between the executor and scheduler, or
* the first task that uses this image to be blocked for a long time to wait for
the container image to be ready.
The solution needs to enable the operator to prefetch a list of "preferred
images" without introducing the above problems.
